Any magazine-cover hack can splash paint around wildly and call it a nightmare, or a witches sabbath or a portrait of the devil; but only a great painter can make such a thing really scare or ring true. That's because only a real artist knows the anatomy of the terrible, or the physiology of fear.
Bunch together a group of people deliberately chosen for strong religious feelings, and you have a practical guarantee of dark morbidities expressed in crime, perversion, and insanity.
The moon is dark, and the gods dance in the night; there is terror in the sky, for upon the moon hath sunk an eclipse foretold in no books of men or of earth's gods.
In its flawless grace and superior self-sufficiency I have seen a symbol of the perfect beauty and bland impersonality of the universe itself, objectively considered, and in its air of silent mystery there resides for me all the wonder and fascination of the unknown.
The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents. We live on a placid island of ignorance in the midst of black seas of the infinity, and it was not meant that we should voyage far.
Pessimists are just as illogical as optimists; insomuch as both envisage the aims of mankind as unified, and as having a direct relationship (either of frustration or of fulfilment) to the inevitable flow of terrestrial motivation and events. That is - both schools retain in a vestigial way the primitive concept of a conscious teleology - of a cosmos which gives a damn one way or the other about the especial wants and ultimate welfare of mosquitos, rats, lice, dogs, men, horses, pterodactyls, trees, fungi, dodos, or other forms of biological energy.
Science, already oppressive with its shocking revelations, will perhaps be the ultimate exterminator of our human species - if separate species we be - for its reserve of unguessed horrors could never be borne by mortal brains if loossed upon the world.
While my chosen form of story-writing is obviously a special and perhaps a narrow one, it is none the less a persistent and permanent type of expression, as old as literature itself. There will always be a certain small percentage of persons who feel a burning curiosity about unknown outer space, and a burning desire to escape from the prison-house of the known and the real into those enchanted lands of incredible adventure and infinite possibilities which dreams open up to us, and which things like deep woods, fantastic urban towers, and flaming sunsets momentarily suggest.
The Old Ones were, the Old Ones are, and the Old Ones shall be. Not in the spaces we know, but between them. They walk serene and primal, undimensioned and to us unseen.
An isolated person requires correspondence as a means of seeing his ideas as others see them, and thus guarding against the dogmatisms and extravagances of solitary and uncorrected speculation.
The one test of the really weird (story) is simply this--whether or not there be excited in the reader a profound sense of dread, and of contact with unknown spheres and powers; a subtle attitude of awed listening, as if for the beating of black wings or the scratching of outside shapes and entities on the known universe's utmost rim.
It is absolutely necessary, for the peace and safety of mankind, that some of earth's dark, dead corners and unplumbed depths be left alone; lest sleeping abnormalities wake to resurgent life, and blasphemously surviving nightmares squirm and splash out of their black lairs to newer and wider conquests.
